Regular readers know that Power Stop is giving away what the company describes as the Ultimate Mustang via a promotional sweepstakes. The pony car in question is a 2017 Mustang clad in Mustang RTR bodywork and filled with the kind of upgrades to back up those looks with performance. Now those upgrades available in two packages from Summit Racing.

“The 5.0-liter Coyote V8 got a bump in power thanks to a Vortech supercharger kit, uprated DeatschWerks 95 lb/hr fuel injectors, and a Magnaflow Competition Series cat-back exhaust system,” Summit explained. “Backed by a custom American Powertrain Tremec TKO six-speed transmission package and tuned by Adam Browne from Revolution Automotive, the GT put down 685 horsepower and 550 lb-ft of torque at the rear wheels.”

In addition to the drivetrain mods, the Power Stop sweepstakes ’Stang’s insides got a performance makeover as well.

“Since the Mustang is intended to be a street/track day car, it got an RTR four-point bolt-in roll cage, a pair of Ford Performance Recaro seats with Schroth Racing Clubman six-point harnesses, and a Barton short-throw shifter,” Summit says.

If these upgrades sound like they might be work on your project, as we mention, Summit is offering them in a nine-piece Performance package (PN SUM-CSUMDMPS004; $10,878.99), which includes Nitto tires, a Vortech supercharger, DeatschWerks fuel injectors and more, as well as a five-piece Interior package (PN SUM-CSUMDMPS005; $5,082.99) highlighted by a set of Recaro seats.
